To answer the idle curiosity part, yes, you can send input to the processes, without bringing it back into the foreground (using fg as others have suggested).

Off the top of my head, one way to do it would be to send data to /proc/<pid>/fd/0. That sends data to file descriptor 0 of the process, which happens to be "standard input".
